ToolBar controls are used to display ToolBarButton controls that can appear as a standard button, a toggle-style button, or a drop-down style button. You can assign images to the buttons by creating an ImageList, assigning it to the ImageList property of the toolbar, and assigning the image index value to the ImageIndex property each ToolBarButton. You can then assign text to be displayed underneath or to the right of the image by setting the Text property of the ToolBarButton.

Set the Appearance property of the toolbar to Flat to give the toolbar and its buttons a flat appearance. As the mouse pointer moves over the buttons, their appearance changes to three-dimensional. Toolbar buttons can be divided into logical groups by using separators. A separator is a toolbar button with the Style property set to ToolBarButtonStyle.Separator. Button separators appear as lines rather than spaces between the buttons when the toolbar has a flat appearance. If the Appearance property is set to Normal, the toolbar buttons appear raised and three-dimensional.

If you specify a value for the ButtonSize property, all buttons in the tool bar are restricted to the specified size. Otherwise, the buttons adjust their size depending on their content, and the ButtonSize property returns the initial size of the largest button.
